Castle Calvay is situated on an islet separated only at high tide from Calvay Island, to which it is linked by a causeway. The fragmentary buildings, built against and incorporating the curtains, are of rough rubble in shell lime mortar. Slabs of stone are in some places bedded on edge. The average height of the walls in 1924 was 12ft. The date is indeterminate.
